JAMES FERGUSON sHARPE, OE TORONTO, OANADA.

BOOT O'R SHOE.

SPECIFICATION forming part of Letters Patent No. 542,175, dated July2,1895.

Application filed April 30, 1894.

To @ZZ whom it may concern:

Be it known that I, .I AMES FERGUSON SHARPE, of lthe city of Toronto, inthe county of York and Province of Ontario, Canada, have inventedcertain new and useful Improvements in Boots or Shoes, of which thefollowing is a specification.

My invention particularly relates to that class of boots and shoes whichare provided with a rubber sole. Hitherto there has been considerabledifficulty experienced in securely attaching the rubberv sole to theleather middle sole, or, in the case of there being no middle sole, tothe insole. y

provide a serviceable bootor shoe having a rubber sole and heel securelyattached to the middle sole or insole, as the case may be, thus adaptingthe boot or shoe for use in all kinds of weather and excluding alldampness from the interior thereof; and it consists, essentially, in thecase of a boot or shoe having a rubber sole and leather middle sole andinsole, in cementing to the upper edge of the rubber sole, when in asoft state, a strip of canvas or other material covered with a coatingof soft rubber, the rubber side of the strip being next to the rubbersole, and vulcanizing the same; in then cementing the leather middlesole on the rub-ber sole, and then turning the rubber-coated stripofcanvas up and over the leather middle sole and cementing itv down on theedge of the leather middle sole.

My invention further consists of a rubber tread for the heel formedintegral with or separate from the rubber sole, the tread being providedwith rubber lugs' or projections adapted to pass through holes in theupper lift or lifts of the leather which form the heel, the rubber treadbeing cemented to the base of the adjoining leather lift aswell as tothe holes formed therein, and preferably also provided with rivets,which pass through the rubber tread and .the lugs formed thereon intothe leather lift or lifts for the purpose of more firmly attaching therubber tread to the superimposed leather lifts.

My invention also consists in the boot or shoe made by the foregoingmethods, as more particularly specified hereinafter and shown in thedrawings.

a portion of the upper and sole broken away. Fig. 2 is a perspectiveView of the rubber sole without the heel-piece, showing the rubbercoatedWelt or strip attached. Fig. 3 is a perspective detail of a rubber treadfor the heel and projections formed thereon. Fig. 4 is a perspectiveView of a rubber tread with projections passing through holes in anadjoining heel-lift. Fig. is a cross-section through the heel. Fig. 6 isa cross-section through the sole.

Like letters of reference indicate corresponding parts in the dierentfigures. The object of my invention is to Overcome this difficulty andto In Fig. l A is the rubber sole, having, preferably, corrugations a. Bis the rubber tread for the heel, and O is a leather heel lift or lifts.Where the boot has been broken away may be seen the rubber-coated stripor welt C, which is attached to the upper edge of the rubber sole and isturned up and over the middle sole E. F is, the upper of the boot, whichis turned in under the insole G and rests on the middle sole and theedge of the rubbercoated strip. I is a filling-piece placed under theinsole and between the turned-in edges of the upper.

l In Fig. 6 may be seen in section, on a large scale, the various partsjust referred to.

. The mannerof attaching the rubber strip to the rubber insole is asfollows: The rubber strip is preferably formed of canvas or othertextile material and rubber-coated on one side. While the rubber sole isin a soft state, and the rubber on the strip also in a soft state, therubber side of the strip is cemented down to the edge of the rubber soleand the rubber sole and strip are then vulcanized. The middle sole isthen cemented onto the top of the rubber sole and. the rubber-coatedstrip is turned up and over onto the top of the middle sole and securelycemented thereto. In some cases I may make the middle sole E andlling-sole I integral, as shown at Fig. 6, in which case the sole isnotched or cut away around the upper edges to receive the uppers. Theedge of the upper is then secured in position on the last with theinsole, and. the rubberouter sole and middle sole are secured throughthe turnedin edge of the upper and insole by means of rivets which areclinched inside the boot. In this mode of construction it is importantthat IOO the rubber-coated strip should be placed on spirit of myinvention, to attach a rubber sole and cemented to the rubber sole, asin the toa boot or shoe made after the ordinary Welt process ofcementing or vulcanizing rubber to rubber holds much more securely. Itisalso important and a leading feature of my invention that therubber-coated strip so attached should be turned upward and over themiddle sole, so that the rubber-coated side of the strip is exposedoutside, andf thus keeps all dampness or moisture from penetratingthrough to the inside of the boot or shoe.

Fig. 2 is a detail of the rubber sole iu which the rubber-coated strip Cis shown cemented and vulcanized to the rubber sole. D showstheinteriorlining of canvas orother textile material. The rubber sole in this caseis shown Without a heel-piece; but if desired a rubber tread may bemolded integral therewith. These rubber soles are molded into standardsizes to suit the respective standard sizes of the leather middle orinsole usually worn. Instead of having a rubber-coated strip cementedand vulcanized to the edge of the rubber sole, the rubber strip or Weltmay be cast or formed integral with the rubber sole.

Fig. 3, a perspective detail of the rubber tread B, shows the lugs orprojections N, formed or cast on the rubber tread. These rubberprojections N may be more or less in number than shown, and may bearranged differently it so desired; but four projections are usuallyconsidered sufficient, and are preferably placed as indicated.

In Fig. 4 the rubber tread and the projections N are shown cemented tothe heel-lift O, the projections N passing through the holes P formed inthe heel-lift.

Fig. 5 is a sectional detail through the heel showing the rubber soleand projections cemented to the adjoining heel-lift O. It desired theprojections may be made longer, so as to pass through more than oneheel-lift. In this View the rubber tread, the heel-lifts, the insole,and the upper are shown riveted together by the rivets H; The heads ofthe rivets H are shown deeply embedded in the rubber in Figs. l, 5, and6, in order to remove them from contact with the ground.

It is possible, without departing from the process.

What I claim as my invention isl. The process herein described ofsecurely attaching a rubber sole to boots or shoes, which consists inconnecting to the rubber sole near its edge a waterproof strip or Weltturning the rubbercoated strip over the edge of the middle sole orinsole and then attaching the rubber sole and rubber-coated strip to thesaid middle-sole or insole, substantially as and for the purposespecified.

2. The process herein described of securely attaching a rubber sole andheel to boots or shoes, which consists in attaching to the rubber solenear its edge a Waterproof strip or welt turning the rubbercoated stripover the edge of the middle-sole or insole and attachingthe rubber soleand rubber-coated strip to the middle-sole or insole, and also inattaching to the heel a rubber tread formed integral with or separatefrom the rubber sole and having lugs or projections formed thereon, andcelneuting them into holes formed to receive them in a leather lift ofthe heel; the Whole being riveted together, substantially as and for thepurpose specified.

3. The process herein described of securely attaching a rubber sole tobootsor shoes which consists, in the case of a. boot or shoe having aleather middle-sole, in cementing to the upper edge of the rubber sole,when in a soft state, a strip of canvas or other material cov ered witha coating of soft rubber, the rubber side ot' the strip being next tothe rubber sole, and vulcanizing the same; in then cementing the leathermiddle-sole on to the rubber sole, and then turning the rubber-coatedstrip ol' canvas up and over the leather middle-sole and cementing it.down on the edge of the leather middle-sole; the rubber sole and theleather middle-sole thus secured together', then being riveted to theinsole and the upper, substantially as and for the purpose specilied.
